热连轧精轧机窜辊系统结构改进

摘要

Because of wear and bad lubrication of equipments , the shifting roll of finishing mill was easily jammed and entry and exit were not synchronized , and it often skipped mode due to large deviation , which made shifting roll cannot be put into normal operation , and influenced the plate shape of finished product seriously .By taking measures such as changing the winding device , joint bearings and clamping plate cylinder at shaft end , the operating rate of shift-ing roll system has reached more than 90%so as to ensure the normal production of finishing mill .%由于设备磨损润滑不良，精轧机窜辊易出现卡阻，入口、出口不同步，经常因偏差过大导致跳模式，窜辊无法正常投入使用，严重影响成品板形。通过采取更改绕动装置、关节轴承、轴端卡板油缸等方案措施，保证窜辊系统作业率达到90％以上，保证了精轧机的正常生产。
